Have you had any warranty issues with your tune? My biggest concern is that I've read that BMW is now flagging cars for potential tunes, even if they come in for something as simple as an oil change.

For that reason I was thinking of going with Carbahn, but I tried contacting them on 3 different platforms and have not received any responses in over a month. Makes you question how their customer service will be if they are not even trying to make a sale.
After I flash an ecu with an aftermarket file I don't take it back to the dealer for oil changes and service and such. With the jb4, I'll just take it off and roll the dice.
